PVM(1PVM)							  PVM Version 3.4							 PVM(1PVM)

NAME
pvm - PVM version 3 console SYNOPSIS
pvm [ -options ] [ hostfile ] DESCRIPTION
Pvm is a stand alone PVM task which allows the user to interactively query and modify the virtual machine. The console can be started and stopped multiple times on any of the hosts in the virtual machine without affecting PVM or any applications that may be running. When started pvm determines if PVM is already running and if not automatically executes pvmd3 on this host, passing pvmd3 the command line options and host file. Thus PVM need not be running to start the console. Once started the console prints the prompt: pvm> The following console commands are available: add hostname(s) - Add hosts to virtual machine alias - Define/list command aliases conf - List virtual machine configuration delete hostname(s) - Delete hosts from virtual machine echo - Echo arguments export - Add environment variables to spawn export list halt - Stop pvmds help [command] - Print helpful information about a command id - Print console task id jobs - List running jobs kill task-tid - Terminate tasks mstat host-tid - Show status of hosts ps -a - List all PVM tasks pstat task-tid - Show status of tasks quit - Exit console reset - Kill all tasks setenv - Display/set environment variables sig signum task - Send signal to task spawn [opt] a.out - Spawn task opts are: -(count) number of tasks, default is 1 -(host) spawn on host, default is any -(ARCH) spawn on hosts of ARCH -? enable debugging -> redirect task output to console -> file redirect task output to file ->>file redirect task output append to file trace - Set/display trace event mask unexport - Remove environment variables from spawn export list unalias - Undefine command alias version - Show libpvm version pvm reads $HOME/.pvmrc before reading commands from the tty, so it can be used to customize the console environment, for example: alias ? help alias j jobs setenv PVM_EXPORT DISPLAY # print my id echo new pvm shell id EXAMPLES
pvm Starts up pvmd3 on the local host or connects to running pvmd3. pvm hostfile Starts up console and pvmd3, which inturn reads the host file and adds the listed computers to the virtual machine. SEE ALSO
